Assessing delays in primary percutaneous coronary intervention for ST-segment elevation myocardial infarction patients at a tertiary care hospital in Sri Lanka: a retrospective cohort study.
Observational study in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo analyse patient profiles, transportation patterns and time delays in ischaemic time and door-to-balloon (DTB) time and evaluate the effect of these delays on in-hospital mortality among patients undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction (STEMI) at a tertiary care hospital in Colombo.
designRetrospective observational study.
settingTertiary care hospital specialising in STEMI treatment, located in Sri Lanka.
participantsThe study included adults aged 16-87 years admitted for P-PCI between January 2018 and September 2023, presenting with STEMI and undergoing emergency P-PCI. Patients with incomplete records or unrealistic values on ischaemic time or DTB time were excluded. OUTCOME MEASURES: Outcome measures include ischaemic time, DTB time and in-hospital mortality. The associations of demographic factors, transfer methods and DTB time with survival rates were analysed.
resultsA total of 1758 patients underwent P-PCI (mean age, 53.0±11.64), with 85.2% being male. The male risk group was 46-60 years (OR, 1.22), whereas the female risk group was predominantly older than 60 years (OR, 1.87). The median ischaemic time was 4 hours and 36 min, and the median DTB time was 110 min. The in-hospital mortality rate was 3.8% (63/1,664). Prolonged DTB times exceeding 120 min were significantly associated with increased mortality (p
conclusionsDespite improvements in DTB times, this study indicates that prolonged delays exceeding 120 min remain associated with increased mortality. Older age and female sex were identified as independent predictors of higher mortality. These findings underscore the need for efficient patient transfer methods and prompt decision-making at the primary healthcare level to minimise delays and disparities in P-PCI outcomes.
